There are a lot of idiomatic expressions with the word ‘milk’.

1. It's no good/use crying over spilt milk.

something that you say which means you should not get upset about something bad that has happened that you cannot change. Sometimes I regret not taking that job in London. Oh well, there's no point crying over spilt milk.

2. The land of milk and honey

a country where people from other countries would like to live because they imagine that the living conditions are excellent and it is easy to make money. People in poorer parts of the world still look on the States as the land of milk and honey.
